The ATLAS inner detector trigger performance in pp collisions at 13 TeV during LHC Run 2
Aad, G.; Abbott, B.; Abbott, D. C.; Abud, A. Abed; Abeling, K.; Adiguzel, A. (SPRINGER, 2022)The design and performance of the inner detector trigger for the high level trigger of the ATLAS experiment at the Large Hadron Collider during the 2016-2018 data taking period is discussed. In 2016, 2017, and 2018 the ... -
Determination of the parton distribution functions of the proton using diverse ATLAS data from pp collisions at root s=7, 8 and 13 TeV
Aad, G.; Abbott, B.; Abbott, D. C.; Abud, A. Abed; Abeling, K.; Cetin, Serkant Ali; Beddall, Andrew John; Ozturk, Sertac (SPRINGER, 2022)This paper presents an analysis at next-to-next-to-leading order in the theory of quantum chromodynamics for the determination of a new set of proton parton distribution functions using diverse measurements in pp collisions ... -
Measurement of b-quark fragmentation properties in jets using the decay B ± → J/ψK ± in pp collisions at √s = 13 TeV with the ATLAS detector
Aad, G.; Abbott, B.; Abbott, D.C.; Abed Abud, A.; Abeling, K. (Springer Science and Business Media Deutschland GmbH, 2021)The fragmentation properties of jets containing b-hadrons are studied using charged B mesons in 139 fb−1 of pp collisions at s = 13 TeV, recorded with the ATLAS detector at the LHC during the period from 2015 to 2018. The ... -
Measurement of the c-jet mistagging efficiency in t(t)over-bar events using pp collision data at root s=13 TeV collected with the ATLAS detector
Aad, G.; Abbott, B.; Abbott, D. C.; Abud, A. Abed; Abeling, K.; Cetin, Serkant Ali (Springer, 2022)A technique is presented to measure the effi-ciency with whichc-jets are mistagged asb-jets (mistaggingefficiency) usingt ̄tevents, where one of theWbosons decaysinto an electron or muon and a neutrino and the other ... -
Search for dark matter produced in association with a standard model higgs boson decaying into b-quarks using the full Run 2 dataset from the ATLAS detector
Aad, G.; Abbott, B.; Abbott, D. C.; Abud, A. Abed; Abeling, K.; Abhayasinghe, D. K.; Abidi, S. H.; Cetin, S. A. (SPRINGER, 2021)The production of dark matter in association with Higgs bosons is predicted in several extensions of the Standard Model. An exploration of such scenarios is presented, considering final states with missing transverse ... -
Search for exotic decays of the Higgs boson into long-lived particles in pp collisions at root s=13 TeV using displaced vertices in the ATLAS inner detector
Aad, G.; Abbott, B.; Abbott, D. C.; Abud, A. Abed; Abeling, K.; Abhayasinghe, D. K.; Abidi, S. H.; Abramowicz, H. (SPRINGER, 2021)A novel search for exotic decays of the Higgs boson into pairs of long-lived neutral particles, each decaying into a bottom quark pair, is performed using 139 fb(-1)of root s = 13 TeV proton-proton collision data collected ... -
Search for heavy particles in the b -tagged dijet mass distribution with additional b -tagged jets in proton-proton collisions at s =13 TeV with the ATLAS experiment
Aad, G.; Abbott, B.; Abbott, D.C.; Abed Abud, A.; Abeling, K.; Abhayasinghe, D.K.; Cetin, S. A. (American Physical Society, 2022)A search optimized for new heavy particles decaying to two b-quarks and produced in association with additional b-quarks is reported. The sensitivity is improved by b-tagging at least one lower-pT jet in addition to the ... -
Search for Higgs boson decays into a pair of pseudoscalar particles in the bbμμ final state with the ATLAS detector in pp collisions at s =13 TeV
Aad, G.; Abbott, B.; Abbott, D.C.; Abed Abud, A.; Abeling, K.; Cetin, S. A. (American Physical Society, 2022)This paper presents a search for decays of the Higgs boson with a mass of 125 GeV into a pair of new pseudoscalar particles, H→aa, where one a-boson decays into a b-quark pair and the other into a muon pair. The search ...
